Poly(p-phenylene sulfide)
Polyphenylene sulfide
(PPS) is an organic
polymer
consisting of
aromatic
rings linked with
sulfide
s.
Synthetic fiber
and
textiles
derived from this polymer are known to resist
chemical
and thermal attack. PPS is used to make
filter
fabric for
coal
boilers
,
papermaking
felts
,
electrical insulation
, specialty
membrane
s,
gaskets
, and
packings
. PPS is the precursor to a
conducting polymer
of the
semi-flexible rod polymer
family. The PPS, which is otherwise insulating, can be converted to the
semiconducting
form by
oxidation
or use of
dopants
.
